Abstract: This invention provides apparatus and a method which self-adjust the pressure response of a digitizer pointing device or other device incorporating a pressure transducer according to the characteristics of the particular device and/or particular user of the device. For example, a digitizer user when inputting with a stylus pointing device may use different writing styles in simulated paint brush and in simulated chalk, or, the user may use the stylus device entirely differently when using it in a game or in a graphic arts application, or different users may use the same stylus device differently for the same application. Certain pressure parameters of the device are not set on a fixed basis, which would provide for an average, typical or generic pressure range and resolution.

Abstract: The present invention solves a number of problems in using stems (canonical indicators of word meanings) in full-text retrieval of natural language documents, and thus permits recall to be improved without sacrificing precision. It uses various arrangements of finite-state transducers to accurately encode a number of desirable ways of mapping back and forth between words and stems, taking into account both systematic aspects of a language's morphological rule system and also the word-by-word irregularities that also occur. The techniques described apply generally across the languages of the world and are not just limited to simple suffixing languages like English. Although the resulting transducers can have many states and transitions or arcs, they can be compacted by finite-state compression algorithms so that they can be used effectively in resource-limited applications.

Abstract: A device applies continuous tension to skin adjacent an ulcerative area, to expand and approximate this skin until it covers the ulcerative area. The new device includes a frame which defines a path in which sliders move under the force of a constant tension spring. Each slider includes a hook-like element that engages and pulls the skin until the skin on opposite sides of the ulcerative area comes together. This element is curved, thus defining a plane which is oriented perpendicular to the path of the slider.

Abstract: In a power supply with a boost pre-regulator and power factor correction devices the voltage induced in an auxiliary winding magnetically coupled to the inductor of the pre-regulator and rectified by a diode bridge charges an integrating capacitor, shunted by a discharging resistor, to a voltage which compared with predetermined reference voltages allows to detect and to signal anomalous operative conditions, such as overload or unoperativeness of the power factor correction devices for the execution of suitable intervention procedures.

Each message containing component comprises a plurality of messages, each of which is specifically related to a particular subject, activity, profession, or area of interest designated by an outfit of wearing apparel.

Abstract: The invention disclosed herein provides nozzles for vessels such as a pressurizer vessel, reactor vessel or piping in a nuclear power facility, and methods for attaching and sealing the nozzles to the vessels without any welding at all, i.e., without using a structural or seal weld. The nozzles are clamped or bolted to the vessel or attached by an interference fit, and a mechanical seal is obtained using gasket material and/or contacting, preferably polished, metal surfaces. Some embodiments of clamping the nozzle to the vessel comprise tightening a nut on the threaded end of the nozzle projecting from the bore in the vessel against the vessel, and structure which prevents the nozzle from being withdrawn through the bore, thereby clamping the nozzle against the vessel. Another embodiment of clamping a nozzle to the vessel comprises a sleeve threaded in the bore and forcing an interfering portion of the nozzle body into engagement with the bore.

Abstract: Toy mold systems usable by a child to form highly detailed, rigid molded toy figures are disclosed. The systems include at least three preformed mold sections each having a configuration such that, in an assembled condition of the toy mold system, they define a mold cavity having at least one undercut. The mold system includes structure for releasably engaging the at least three mold sections in the assembled condition of the toy mold system. In the preferred embodiments, the mold system includes a base, top, and four wall mold sections. One, and preferably all, of the wall sections have a cavity portion with undercuts which provide the detailing on the sides, front and back of the molded toy figure. One of the mold sections functions as a base section into which the other mold section nest and with which they are releasably engaged.

Abstract: A stylus for use with a digitizer tablet has a tip element that includes a front portion with a tip for engaging the surface of the tablet, and a back portion of the tip element within the stylus housing. The back portion of the tip element is adapted to apply pressure to a pressure sensitive resistance element. The front and back portions of the tip element are coupled together by a spring, in order that the tip element be resiliently compressible in the axial direction of the stylus.

Abstract: A suspension device in a crawler vehicle has a vehicle body, a pair of parallel spaced swing beams mounted on a rear portion of the vehicle body by a suspension for angular movement about a first axis located substantially longitudinally centrally thereof, a rear idle wheel rotatably supported on a front portion of each of the swing beams for rotation about a second axis, a rear drive wheel rotatably supported on a rear portion of each of the swing beams for rotation about a third axis, a crawler belt trained around the rear idle wheel and the rear drive wheel, and a front wheel rotatably mounted on a front portion of the vehicle body. The distance from the second axis to the first axis is greater than the distance from the first axis to the third axis. The second axis is positioned on a front end of each of the swing beams, and the third axis is positioned between the first axis and a rear end of each of the swing beams.

Abstract: When a cylinder unit is actuated to extent its rod upwardly, a chuck is lifted above an inner cup to receive a planar workpiece such as a semiconductor wafer or a glass substrate. The chuck is now disengaged from the inner cup, and a stopper locks the chuck against rotation. After the planar workpiece has been supported on the chuck, the cylinder unit is actuated to retract its rod, bringing the chuck into its lowered position. The chuck is now engaged by the inner cup for corotation. Energization of a motor rotates the inner cup, which then rotates the chuck. Since the inner cup, which has a relatively large rotational inertia, is driven by the motor, interengaging portions of the inner cup and the chuck are less susceptible to damage.

Abstract: A graphical editing system is provided which creates a "place-holder" that holds or suspends a complex gesture or complex menu selection before committing to the command. Such a place-holder acts as a virtual stylus, i.e. as if the user was actually holding the stylus to the screen just prior to committing to the command. The virtual stylus thus allows the user to execute other arbitrary drawings or menu commands or gestures while the original complex command is suspended. The user can then return to the complex command he/she chooses and remove the place-holder to commit to the command or cancel the command if desired. The virtual stylus can take on many forms, e.g., a hand with a pointed finger, an icon or any other desired indicator, and the virtual stylus can be created by any user action, e.g., an actuated stylus button, pressure sensitive display surface or by sensing the time during which the stylus remains stationary on the display screen. The virtual stylus can be removed in basically the same way.

Abstract: A multi-user multi-device system enables a plurality of users to control a single screen. Each user has one or more input devices, which can be used to control one or more stored applications. At any time, the system produces a consistent view of all applications on the single screen. The input from each user produces a response customized to the preferences of that user. Each user can inform the system of which devices that user is using. Inputs to the system initiate the building of Event Records that are queued and then directed to specific applications. The screen is updated, and the coordinates of child applications are determined, only during pauses in the operations of all applications.
